GLOBE data can be viewed in World Wind through the WMS (Web Map Service) browser by following these steps:

Start up World Wind with the world called "Earth". (This is the default. Other available worlds include the Moon and Mars.)

In the top menu bar, click the WMS Browser icon (see figure 1). This takes a while to load and brings up a window with two servers listed, NASA SVS Image Server and The GLOBE Program Visualization Server.

Click the "+" sign next to The GLOBE Visualization Server to expand the hierarchy, then click the "+" signs next to the data category of interest (e.g. Air Temperature) until the desired dataset is seen (see figure 2).

Once a dataset is selected, you can either:

View the dataset for a particular date by clicking the "Still Image" button; or

Animate the dataset over some length of time by choosing the "Animation" tab in the lower half of the box; select a date range and click on the play button at the bottom of the box.

The data points are now being displayed on the world image. As you click on the Earth it will turn or spin in the direction of the click and will display the new data points as they are available (see figure 3).

The GLOBE Program (Global Learning and Observations to Benefit the Environment) is a worldwide hands-on, primary and secondary school-based education and science program. It is an interagency program funded by the National Aeronautics and Space Administration (NASA) and the National Science Foundation (NSF), supported by the U.S. Department of State, and implemented through a cooperative agreement between NASA, the University Corporation for Atmospheric Research (UCAR) in Boulder, Colorado and Colorado State University in Fort Collins, Colorado. GLOBE is a cooperative effort of schools in partnership with colleges and universities, state and local school systems, and non-government organizations. Internationally, GLOBE is a partnership between the United States and over 100 countries that manage and support their unique national and regional program infrastructure and activities.
